Mechanical Repair

Mechanical repair workships are one of the most energy efficient amongst the automotive industry with lighting, air compressor and heating ventilation and air conditioning (HVAC) being the major contributors to electricity bills. An audit of mechanical repair workshops in metropolitan and regional areas of Victoria and Tasmania identified that an average mechanical workshop uses 27,668 kWh of electricity per year. That is an average cost of $8,258, more than hald of the industry’s average per year.

Whilst mechanical repair workshops use significantly less electricity compared to other automotive industry sectors, there are many energy saving opportunutues that can be made which could potentially save businesses hundreds of dollars.
